| abstract |
The invention discloses a kind of hybrid cross-linked dynamic aggregation object, the covalent cross-linkings for acting on containing metal-ligand and being formed by covalent bond, wherein more than the gel point that covalent cross-linking reaches covalent cross-linking at least one cross-linked network.Such dynamic aggregation object combines metal-ligand effect and the respective advantage of covalent cross-linking, and by the regulation to reaction materil structure, can prepare structure-rich, the polymer material of performance multiplicity.Metal-ligand acts on the dynamic reversibility that has in dynamic aggregation object, so that polymer reflects the functional characteristics such as stimulating responsive, the effects of selfreparing, shape memory, toughening are played to material in specific structure；And covalent cross-linking imparts polymer with certain strength and stability.The dynamic aggregation object can be used as self-repair material, toughness material, sealing material, shape-memory material, force snesor material etc. and is widely applied. |
